- I M PRovEfM ENT 'm LAM Pse To all wioifn, it may concern.'

Be it known that I, MARTlN RAE, ofthe city of Manchester, in the county of Lancaster and Kingdom of'Great Britain,have invented a new and useful Improvement in Lamps; -and I do hereby declare'j'that the following is a'full, clear, and exact description ofthe same, reference being' had to the accompanying drawin s, making a part of this specification, in

Figure 1 is an external view of my invention.; Fig, 2, a vertical central section lof the same, taken inthe l-ine a; w, Fig. 1. 4

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists in causing a current of air to impinge against the flame of a lamp by means. of a lamp,- taper, light, or other, heatlproduci'ng agent placedwithin or under a tube or tubes communicating with the burner", which, en -being lighted or heated,

inV contact with th'e'ame ofthe lamp, produces a white light.-

To enable those skilled inthe art to fully proceed to describe it.

A represents the fountain of the lamp, which lmay be made of glass, met-al, or other suitable material.l This fountain has a tub'er B, passing through-it, and open at both ends,

fitted, the fountain being secured to the tube G by-arms a. The tube C is considerably smaller in diameter than the tube B, to allow a space, b, of requisite width between them,

D is the wick-tube, which `is placed cenand communicates at its lower end withl the fountain A'by a tube, E. The upper end of Hector, F, andthe top of the tube O is cov-Y ered by a piece of wire gauze or cloth, 'GA The tube C extends down below thefountain A, and it is connected by rods c c to the base H of the lamp, in which basca small lamp', I, is fitted. The'base H has al'perforated bottom, d, and also perforated sides e, through which air passes to feed the flame of lamp 1 and also tofeed the iiame of the wick-tube D, which is the illuminating-dame.

On the base H there is placed a shell or case, J, which extends some distance upward'i on the tube C and for-ms a'chmber above'the base H. The tube C extendsaqtriiieabove.

the fountain A, so that the latter will not cast' a shadow at any considerable distance 'from p thebaseH.

The operation will be readily understood.4

The lamp I, when lighted, rarees the air in tube C and'induces a draft therein, (see black' arrows,) which impinges against the flame of the wick-tube D andsupplies it with a requif.

emission -of smoke.. or any unpleasant odor;l

A glass chimney may be used or not, as deg sired.

The lamp constructed as described is applicable for 'burningwhat is commonly termedr flight oils,I andv thespace b between the tubes B C admits of a current of air passing up, as indicated by the blue arrows, to keep the oil .in a cool state, or suieientlyl soto prevent undue volatilization. -For heavy oils,

the fountain A is not provided with the tube B, the tnbeC being` in direct Contact with the fountain, in order'tocause the-'oil to be volatilized suiiciently to keep the flame of the wick-tube D properly supplied with vapor.-

The lamp I may be supplied with anysuitable burning material. 4 A taper may be'used instead, or any heat-producing agent.

I do not confine myself to the form of the parts herein described,'.nor .to the precise arrangement of the same, for these may be varied and modified in'va'rious'waysi andthe same end attained.

I de not claim the exclusive use of any of the parts" of the-lamp herein described when separately considered; but, Having thus described my i-nventiomwhat I do claim as-new, and desire to secure by Let-P ters Patent, is*

Theemployment or use of a'lighted lamp, taper, :or other heat-producing agent at the' bottom of or into lthe air-tube or air-tubes of the lamp, arranged to operate in the manner as and for the purpose herein set forth'.4
